Note 2:
Long-term input offset voltage stability refers to the averaged
Note 7:
The average input offset drift performance is within the trend line of offset voltage vs time over extended periods after the fi rst specifi cations unnulled or when nulled with a pot having a range 8kΩ to 30 days of operation. Excluding the initial hour of operation, changes 20kΩ. in VOS during the fi rst 30 days are typically 2.5μV. Refer to the typical
